Alkaline batteries are a common sight in most households. AA, AAA, 9-volt batteries, and C and D batteries are all alkaline batteries. These batteries have a long shelf life, they're convenient, and they can be recharged in many instances. However there are definite dangers associated with alkaline batteries that anyone who uses them should be made aware of.

Equipment Dangers

Alkaline batteries contain acidic liquids, gels or pastes, depending on the variety of battery. These acidic cores are surrounded by several layers of insulation and then the outside case of the battery keeps them sealed. However if these batteries develop a leak while they're inside a piece of electronic equipment, such as a television remote, radio or a camera, then chances are that they will completely destroy that piece of equipment. For this reason, batteries should be checked occasionally, and if an appliance isn't going to be used for more than two months, the batteries should be removed.

Skin Dangers

The contents inside alkaline batteries are extremely dangerous to a person's skin and eyes. These acidic compounds may leak out of batteries while they're being handled, or they may burst out of a battery that's been put under too much heat and pressure (this is especially dangerous if batteries are exposed to open flame). If you are exposed to the innards of an alkaline battery, sluice the area with water immediately to minimize the damage. This is especially true if battery acid gets into your eyes.

Environmental Dangers

Alkaline batteries are extremely harmful to the environment if they aren't disposed of properly. If these batteries burst in a landfill, their contents can damage surrounding plants and contaminate the soil so that nothing will grow there. Animals often mistake alkaline batteries for food and eat them, and these animals die when the batteries burst in their stomachs. Additionally, the acidic compounds from alkaline batteries can leak into the water table, poisoning the ground water in an area so that no one can drink it safely.
